Body comparison: Canon G7 X vs T6i

The physical size and weight of the Canon G7 X and the Canon T6i are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the G7X – represents the basis for the calculations across all the size and weight measures).

Compare G7X or T6i rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T6i is considerably larger (116 percent) than the Canon G7 X. In this context, it is worth noting that neither the G7X nor the T6i are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X has a lens built in, whereas the T6i is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the T6i and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the G7X gets 210 shots out of its NB-13L battery, while the T6i can take 440 images on a single charge of its LP-E17 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G7X was launched at a lower price than the T6i, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.

 

Sensor comparison: Canon G7 X vs T6i

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G7 X features an one-inch sensor and the Canon T6i an APS-C sensor. The sensor area in the T6i is 186 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon G7 X and Canon T6i sensor measures

With 24MP, the T6i offers a higher resolution than the G7X (20MP), but the T6i nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G7X) due to its larger sensor. Moreover, the T6i is a somewhat more recent model (by 4 months) than the G7X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The T6i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Canon PowerShot G7 X has a native sensitivity range from ISO 125 to ISO 12800 The corresponding ISO settings for the Canon EOS Rebel T6i are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600..

G7X versus T6i MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

It is notable that the T6i has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G7X does not feature such a mic input.

Both the G7X and the T6i have been discontinued, but can regularly be found used on eBay. The G7X was replaced by the Canon G7 X Mark II, while the T6i was followed by the Canon T7i.


Review summary: Canon G7 X vs T6i

So how do things add up? Which of the two cameras – the Canon G7 X or the Canon T6i – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon PowerShot G7 X:

  • More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
  • Faster burst: Shoots at higher frequency (6.5 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with a built-in lens, while the T6i requires a separate lens.
  • More compact: Is smaller (103x60mm vs 132x101mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the T6i).
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been on the market for longer (launched in September 2014).


Arguments in favor of the Canon EOS Rebel T6i:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (440 versus 210) out of a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More modern: Was introduced somewhat (4 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the T6i emerges as the winner of the match-up (11 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

G7X 08:11 T6i

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G7X and the T6i in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
